QML property list empty when accessed from C++
-
Good afternoon,
How can a qml property list be accessed from C++ side?
I think an example should make things clear:
@
// MyItem.qml
Rectangle
{
// some properties
}// MyComponent.qml,
CppComponent // available through qmlRegisterType<CMyComponent>("myComponents", 1, 0, "CppComponent");
{
width: 100
height: 62property list<MyItem> myItems;
}
@@
// Usage.qml
Rectangle
{
width: 100
height: 62MyComponent { myItems: // <--- the property list gets filled here [ MyItem { x: 100 y: interpolator.rotationCenter.y width: 150 height: 200 }, MyItem { x: 100 y: interpolator.rotationCenter.y width: 150 height: 200 } ] }
}
@The big question is: how can the property list be accessed from C++
side?My stupid approach was:
@
QQmlListProperty<QQuickItem> mis = this->property("maskItems").value<QQmlListProperty<QQuickItem> >();
@because
@
this->property("maskItems").typeName();
@returns "QQmlListProperty<MyItem_QMLTYPE_0>"
But the list is empty...
I also tried a QList<QQuickItem *>, QVariantList and some other stupid things
I cannot remember anymore but it's the same all the time:
no items are contained in the list when it is accessed from C++ sideWhat's wrong here?
Thank you in advance,
Martin
